The generator matrix

 1  1  1  1  1  1  1  1  2  2  0  4  2  2  1  1
 0  2  4  6  0  6  4  2  6  2  2  2  0  4  0  4

generates a code of length 16 over Z8 who´s minimum homogenous weight is 16.

Homogenous weight enumerator: w(x)=1x^0+25x^16+4x^18+2x^20

The gray image is a code over GF(2) with n=64, k=5 and d=32.
